The
red
line is the route actually walked: it deviates sometimes from the blue lines to avoid obstacles such as thick bracken, gorse, bogs or clitter, and often to use paths or
animal tracks that are not on the map. It may also be shorter than the planned
(blue) route if the walk is curtailed for some reason.

NB - There is a slight locational mis-match in
this red track in that it should show a straight line across the viaduct,
between the P
symbol and the blue "70" on the map.blue "70" on the map.

The roads via Yelverton and Horrabridge are main
roads. Parking was at the P symbol on the map where a
large car park is located on the left of the road just before the bridge where
it crosses the River Walkham en route to Tavistock.
